Troubleshooting

1) Checked and found Microsoft
Software Shadow Copy Provider Service was missing from services
console.
2) Tried to take System State
Backup of the server, however it failed with the
error.
3) Checked and found that the
Registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WSPRV entry
is missing as well.
4) Tried to register it using
regsvr32 /i swprv.dll but got the error.
5) Ran the command
C:\Windows\System32\svchost.exe -k swprv (this will load the dll and Recreate
the service)
6) Found “Microsoft Software
Shadow Copy provider service” is still not
present.
7) Ran the following commands:
Regsvr32 C:\Windows\System32\vss_ddu.dll
Regsvr32 C:\Windows\System32\ES.DLL
Regsvr32 C:\Windows\System32\EVENTCLS.DLL
Regsvr32 C:\Windows\System32\vssui.dll

Regsvr32 C:\Program Files\Microsoft SQL Server\80\COM\sqlvdi.dll

8) Replaced swprv.dll from working machine.
9) Found now we have swprv present in the registry.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\swprv
10) Ran the following commands:
regsvr32 ATL.dll
regsvr32 swprv.dll
11) Checked and found now we also have “Microsoft Software Shadow Copy Provider Service” under services.msc console.
12 ) Took System State Backup of the server successfully.
